UF4005-E3

Vishay Intertech · Diodes - General Purpose · DO-41

UF4005-E3 from Vishay Intertech, in a DO-41. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, the end marked by the color band; the device blocks up to VRRM 600 V (UF4005) and conducts 1.0 A average forward current.
2 A passive Anode, the end without the color band; the single-die rectifier conducts forward with VF 1.7 V max at 1.0 A (UF4005).
